Embodiment 1

[0051] see image 3, a connection structure of a coaxial cable on a PCB board provided by Embodiment 1 of the present invention includes a coaxial cable 10 and a PCB board 20, wherein the first end and the second end of the coaxial cable 10 are not connected The core wires at both ends are stripped out and exposed outside. The core wire at the first end of the coaxial cable 10 is welded to the first soldering point 31 on the PCB 20 , and the core wire 12 at the second end is soldered to the second soldering point 41 on the PCB 20 . Specifically, the PCB board 20 is mainly used for mobile terminals such as mobile phones and smart watches, on which an antenna 40 and a radio frequency module 30 are arranged, the first soldering point 31 is a soldering point corresponding to the radio frequency module 30, and the second soldering point 41 is The soldering point corresponding to the antenna 40 . The antenna 40 is printed on the PCB board 20 .

Embodiment 2

[0053] see Figure 4 , a connection structure of a coaxial cable on a PCB board provided by Embodiment 2 of the present invention, and image 3 The difference between the two embodiments is that the core wire 11 at the first end of the coaxial cable 10 is exposed, and the second end of the coaxial cable 10 has a connector male seat 13 . The core wire 14 at the first end is welded to the first welding point 31 on the PCB 20 , and the male connector 13 is connected to the female connector 42 on the PCB 20 . Specifically, the PCB board 20 is mainly used for mobile terminals such as mobile phones and smart watches, on which an antenna 40 and a radio frequency module 30 are arranged, the first soldering point 31 is a soldering point corresponding to the radio frequency module 30, and the male connector seat 15 is The antenna connector male seat, the connector female seat 32 is the antenna connector female seat.

Embodiment 3

[0055] Embodiment 3 of the present invention also provides a method for connecting a coaxial cable on a PCB, wherein neither the first end nor the second end of the coaxial cable 10 has a male connector seat or a female connector seat. The core wire 14 of end is exposed outside, and this method comprises:

[0056] Solder the core wire 11 of the first end of the coaxial line to the first welding point 31 on the PCB board 20;

[0057] Solder the core wire 12 of the second end of the coaxial cable to the second soldering point 41 on the PCB 20 .

[0058] Specifically, the PCB board 20 is mainly used for mobile terminals such as mobile phones and smart watches, on which an antenna 40 and a radio frequency module 30 are arranged, the first soldering point 31 is a soldering point corresponding to the radio frequency module 30, and the second soldering point 41 is The soldering point corresponding to the antenna 40 . The antenna 40 is printed on the PCB board 20 .

Abstract

The invention discloses a connecting method structure for a coaxial cable on a PCB, wherein the core wires at two ends of a coaxial cable are exposed to the outside. The method comprises the steps: welding the core wire at the first end of the coaxial cable to a first welding point on the PCB; and welding the core wire at the second end of the coaxial cable to a second welding point on the PCB. The connecting method structure for a coaxial cable on a PCB can save a connecting seat and reduce the cost of the whole machine. Besides, the connecting method structure for a coaxial cable on a PCB can also simplify the technology and reduce the total thickness of the PCB.

Description

technical field [0001] The invention relates to the field of PCB design, in particular to a connection method and structure of a coaxial cable on a PCB. Background technique [0002] Coaxial cables, also known as cables, are widely used in some mobile terminals, such as mobile phones and smart watches. In the prior art, a male connector seat is provided at both ends of the coaxial line, and the male connector seat is connected to a female connector seat on the PCB. On the one hand, this connection method is costly, and on the other hand, it increases the height of the device, which is not conducive to the thinning requirements of the handheld device. Contents of the invention [0003] In view of this, the present invention provides a connection method and structure of a coaxial cable on a PCB, which saves the connection seat and reduces the cost of the whole machine. In addition, the process can be simplified and the total thickness of the PCB board can be reduced. [0...
